Based on the changes in different versions of texts, this paper discusses the issue of homogeneous texts and their translations at the theoretical level, and introduces the homogeneous texts in Mao Zedong's works and their English translations. On that basis, the paper describes the design and creation of the Chinese-English Composite Corpora of Homogeneous Texts by Mao Zedong, and introduces the basic information, research models and application areas of the corpora. Compared with parallel corpora in the general sense, the Chinese-English Composite Corpora of Homogeneous Texts by Mao Zedong can be used to examine the changes between homogeneous texts, and relevant findings can not only explain the discrepancies between different translations, but also shed new light on many relevant research areas, including the studies of Mao's discourse, the studies of Mao's thought, the studies of China's national image construction from diverse perspectives.
